The InPen is a great solution...

“The InPen is a great solution to the real world problem of people with diabetes. It provides exactly what's needed: time and dose, how much insulin activity remains at a particular time, and an accurate history… a perfect solution.”

Closes the capability gap...

“Having insulin dosing information for patients on multiple daily injection therapy would be very helpful to me as a provider making management decisions. More importantly, it will close the capability gap between injection and pump therapy, bringing many of the benefits of a pump (bolus calculator, insulin-on-board) to the vast majority of patients who do not use one. ”

InPen fills an unmet need...

"Despite the availability of pumps and pens, which are both important products, there remains an unmet need for the majority of folks who use pens to deliver their basal and meal time insuIin. Insulin pens should have many of the features and advantages the pump wearers enjoy. InPen fills this need in a simple and intuitive way, something I personally and many of my colleagues with type 1 diabetes appreciate. I look forward to being able to provide my patients the option of a dose calculator and automatic logging in the form factor of a pen."
